The embodiment of the present invention uses a simulated method to pass the primary color and white point (white balance) chromaticity coordinates in the experimental example and a 1352943 primary color in the four primary color simulation environment. The difference between the color gamut formed by the LCH coordinate system and the natural color gamut is observed with respect to the change of the white brightness ratio, and then the relative brightness of each primary color of the multi-primary color display and the coverage of the natural color gamut are summarized. More specifically, in the three-dimensional space of the LCH coordinate system, the shape of the Gamut boundary (that is, the color gamut range formed by the experimental example) may vary due to the relative brightness ratio of each primary color. Change. Fig. 1 and Fig. 2 are gamut space diagrams of two experimental examples obtained according to the above simulation steps, to illustrate that changing the relative brightness ratio of each primary color in the experimental example allows the gamut range formed by the four primary colors to be self-contained The color gamut range is well covered. In the two figures, 'large area dark surface 1 () 2, 202 is the gamut range formed by the four primary colors' and grid-like areas 1 〇 4, 204 are natural The color gamut range, which is exposed by the gamut range of 1 〇 2, 202 which is not formed by the four primary colors. As shown in the figure, 'Compared with two experimental examples with different relative color ratios of the primary colors' The color gamut range formed by the experimental example is significantly better than the color gamut range formed by the experimental example of FIG. 2 . FIG. 3 is a schematic view showing a display device according to an embodiment of the invention. The device 300 includes a plurality of halogens 302. Each of the halogens 3〇2 has at least four secondary halogens 312', wherein the secondary monomers 312 respectively display a red primary color (R), a green primary color (G), and a blue primary color (B). And a new primary color (V). For example, the display device 300 herein may be a flat display, such as a self-illuminating display device (such as an organic electroluminescent display, etc.), or a display device requiring a backlight (such as a liquid crystal display). Figure 4 is another embodiment of the present invention. A flow chart showing a manufacturing method of the event 1352943 is provided. For the following description, please refer to Fig. 3. A plurality of halogens 302 are formed to form a halogen array (step 402). Each element 3〇2 has at least four a sub-pixel 312, wherein the sub-pixels 312 respectively display a red primary color (R), a green primary color (G), a blue primary color (B), and a new primary color (V). For example, when the display device 300 requires backlighting In the case of a source display device, a color filter layer and a switch (not shown) may be combined to form a halogen element 3 (step 404). The switch may be a liquid crystal element or other suitable optical switch (1) shutter element. Moreover, these pixels 3〇2 are disposed on one side of the backlight (not shown) of the display device 3 (step 406), thereby displaying the red primary color, the green primary color (G), and the blue primary color (B). And the new primary colors (v). The following two examples use the method of the above simulation. In the simulation, each group of experimental examples first assume the relative brightness of the new primary color (green or yellow) (for example, 0.1, 0.2, or 〇.3), and then use equation (1) to find the red, green, and blue primary colors. Relative brightness. Then, 'the color gamut range formed by this set of experimental examples is observed to cover the natural color gamut to determine whether it meets the requirements. According to this, the results obtained by simulations of multiple sets of experimental examples can be obtained from the coating of the t-color gamut and the balance of various color coatings (4), respectively, to obtain different new primary colors and red, green and blue originals respectively. The size relationship between colors. + Difference_An embodiment FIG. 5 is a graph showing the relationship of the first brightness of the present invention, wherein the vertical axis is tamping: the ratio of the relative Q brightness of the different experimental examples is the number of the 273 experimental examples. In Fig. 5, 'line 502 is the relative luminance of the red primary color, line 5〇4 is the relative π degree of the green primary color, line 506 is the relative luminance of the blue primary color, and line 5〇8 is the relative luminance of the cyan primary color. _ χ 之 chromaticity coordinates Υ axis chromaticity coordinates red primary color 0.696 0.29 green primary color 0.268 0.686 blue primary color 0.135 0.075 blue primary color 0.148 0.429 white point 1 0.313 0.329 white point 2 0.28 0.29 Table 1: reference chromaticity coordinate table of each primary color The reference chromaticity coordinates of each primary color are listed, and each set of experimental examples selects the chromaticity coordinates of the primary colors used in the experimental examples from around the reference chromaticity coordinates for simulation. Under the consideration of the coverage of the natural color gamut and the balance of various color coatings, the experimental examples that meet the requirements are shown in Figure 5. As can be seen from Fig. 5, when the new primary color is cyan, the relative brightness between the primary colors is: green primary color relative brightness > red primary color relative brightness > cyan primary color relative brightness > blue primary color relative brightness>> and, 0.162 $ Red primary color relative brightness 388; 1352943 - Ο.315 $ green primary color relative brightness $0.709; - 0·003 $ blue primary color relative brightness $0.197; and 〇·1 S green primary color relative brightness 3. Second Embodiment: FIG. 6 is a view showing a relationship between relative brightness of different experimental examples according to a second embodiment of the present invention, wherein the vertical axis is a ratio φ of a primary color to white brightness (ie, relative brightness), The number of the experimental examples of 152 groups in Hengdao County. In the 6th::' line 602 is the relative brightness of the red primary color, the line 6〇4 is the relative immunity of the green primary color, the line 606 is the relative brightness of the primary color of the basket, and the line 6〇8 is the relative brightness of the yellow primary color. X-axis chromaticity coordinate Y-axis chromaticity coordinate primary color 0.692 0.28 Green primary color 0.208 0.672 Blue primary color 0.125 0.055 Yellow primary color --------- __0.499 0.493 White point 1 __0.313 0.329 White point 2 _ 0.28 0.29 Table Two: the reference chromaticity coordinates of each primary color listed in the reference chromaticity coordinate n table of each primary color, each set of experimental examples will select the chromaticity coordinates of each primary color used in the experimental example from the vicinity of the two reference chromaticity coordinates. For simulation purposes. In the coverage of the natural color gamut 12 1352943 and the balance of various color coatings, the experimental requirements are shown in Figure 6. As can be seen from Fig. 6, when the new primary color is a yellow primary color, the relative luminance between the primary colors is: green primary color relative brightness > yellow primary color relative brightness > red primary color relative brightness > blue primary color relative brightness. ~ & Moreover, 0.068 S red primary color relative brightness % 247; 0·307 $ green primary color relative brightness $0.764; 0.03 7 $ blue primary color relative brightness % 192; and 0·1 $ yellow primary color relative brightness S0.3. In summary, it can be seen that although the selection of the chromaticity coordinates of the respective primary colors may vary depending on process capability, material limitations, or other reasons in each embodiment, the relative brightness of the respective primary colors is the same. Brightness blending that violates this size relationship, although it is possible to obtain a larger color gamut range, will be somewhat degraded in overall performance, and may not be saturated enough in certain specific colors. Therefore, the 'simulation process of the above embodiment' can avoid the blind spots that may be generated when observing the size of the two-dimensional space gamut on the CIE1931 chromaticity coordinate map, and can adjust the primary colors according to different purpose requirements. Good relative brightness ratio. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and it is to be understood that the invention may be practiced otherwise without departing from the spirit and scope of the invention. The scope of protection of the present invention is defined by the scope of the appended claims. [Simple description of the map]
